Spring 注解 事务

1、Spring项目中事务手动回滚：

TransactionAspectSupport.currentTransactionStatus().setRollbackOnly();

或者抛出异常：

	@Transactional(rollbackFor = { Exception.class, RuntimeException.class })
	public HousingFundDto slogin(){
		try {
...
throw new BusinessException("无法查询基本信息");
...}catch (BusinessException e) {
			throw new BusinessException(e.getErrorDesc());
		} 

}

2、

 /**
     * 更新
     */
    @Transactional(rollbackFor = { Exception.class, RuntimeException.class })
    public void update(Entity entity) {
        targetDao.update(entity);
    }

    /**
     * 新增
     */
    @Transactional(rollbackFor = { Exception.class, RuntimeException.class })
    public void insert(Entity entity) {
        targetDao.insert(entity);
    }
